Instruction
Thank you for purchasing a Canon product.
The Canon EF14mm f/2.8L II USM is a highperformance super wide-angle lens designed
for EOS cameras.
¡“USM” stands for Ultrasonic Motor.
C
Features
1. Aspherical and UD lens elements result in
outstanding image delineation.
2. Ultrasonic motor (USM) for fast, quiet
focusing.
3. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
4. Close-up photography up to 0.2 m/0.7 ft.
5. A truly round aperture hole results in a nicer
background blur.
6. Tight seal structure ensures excellent dustproof and drip-proof performance.

a Safety Precautions
a Safety Precautions
• Do not look at the sun or a bright light source
through the lens or camera. Doing so could result
in loss of vision. Looking at the sun directly through
the lens is especially hazardous.
• Whether it is attached to the camera or not, do
not leave the lens under the sun without the
lens cap attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a
fire.
Handling Cautions
C
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Do not make any changes or modifications to the equipment
unless otherwise specified in the instructions. If such changes or
modifications should be made, you could be required to stop
operation of the equipment.
This equipment has been tested and found to comply with the
limits for a class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Consult the dealer or an experienced radio/TV technician for
help.

• If the lens is taken from a cold environment into
a warm one, condensation may develop on the
lens surface and internal parts. To prevent
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
warm environment. Then take out the lens after it
has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
• Do not leave the lens in excessive heat such as in
a car in direct sunlight. High temperatures can
cause the lens to malfunction.
This Class B digital apparatus complies with Canadian ICES-003.

1. Mounting and Detaching the Lens
See your camera’s instructions for details on
mounting and detaching the lens.
¡After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
electrical contacts from getting scratched.
¡If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
¡If the contacts get soiled or have fingerprints on
them, clean them with a soft cloth.
¡If you remove the lens, cover it with the dust
cap. To attach it properly, align the lens mount
index and the K index of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.
C
See the diagrams below for directions for
removing and attaching the lens cap.

The lens mount has a rubber ring for enhanced
water- and dust-resistance. The rubber ring may
cause slight abrasions around the camera's lens
mount, but this will not cause any problems. If the
rubber ring becomes worn, it is replaceable by a
Canon Service Center at cost.

To shoot in autofocus mode, set the focus mode
switch to AF.
To use only manual focusing, set the focus mode
switch to MF, and focus by turning the focusing
ring. The focusing ring always works, regardless
of the focus mode.
C
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual
focus)
To compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.
For accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.
ENG-5
4. Infrared Index
5. Depth-of-Field Scale
Y
P
O
The infrared index corrects the focus setting
when using monochrome infrared film. Focus on
the subject manually, then adjust the distance
setting by moving the focusing ring to the
corresponding infrared index mark.
C
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
¡The infrared index position is based on a
wavelength of 800 nm.
¡Be sure to observe the manufacturer’s
instructions when using infrared film.
¡Use a red filter also when you take the picture.
The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale. The numbers on the
scale are F values, and for example, if the
shooting distance is 0.5m and the aperture is
f/16, the area in focus will extend from about
0.3m to infinity.
The depth-of-field scale is an approximate
indicator.

6. Filter Holder
Y

O
There is a gelatin filter holder at the rear of the
lens. Cut the gelatin filter to fit within the white
frames. Then insert the gelatin filter into the filter
holder.
C
¡Only one filter can be used.
¡When you use a gelatin filter, ghosting may
appear in the image.
